Pear tree named ‘NC4’

ABSTRACT

‘NC4’ is a new and distinct variety of pear tree (Pyrus communis), selected from seedlings produced as the result of a cross between female parent ‘Concorde’ (U.S. Plant Pat. No. 9,192) and male parent ‘Red Williams’ (not patented). ‘NC4’ is distinguished by its fruit, the skin overcolor of which is purple at harvest, turning to red and orange-red upon ripening.

Latin name: Pyrus communis.

Variety denomination: ‘NC4’.

BACKGROUND OF THE VARIETY

‘NC4’ is a new and distinct variety of pear tree (Pyrus communis), selected from seedlings produced as the result of a cross made in 2007 between female parent ‘Concorde’ (U.S. Plant Pat. No. 9,192) and male parent ‘Red Williams’ (not patented). ‘NC4’ was selected and first asexually propagated by budding 2008, and has been observed to remain true to type over successive asexually propagated generations. The original cross, selection and subsequent asexual propagation of the new variety were carried out at Staplehurst, Tonbridge, Kent, United Kingdom.

‘NC4’ is distinguished by its fruit, the skin color of which is red-purple at harvest, turning to red-orange upon ripening. Comparisons of ‘NC4’ to its parents and similar variety ‘Sweet Sensation’ (not patented) are set forth in the following tables.

BOTANICAL DESCRIPTION OF THE VARIETY

The following botanical description is based on observations made during the 2016 and 2017 growing seasons at Seiches sur le Loir, France of two- and three-year-old trees grown on ‘SYDO’ rootstock (not patented). All colors are described according to The Royal Horticultural Society Mini Colour Chart (2005). It should be understood that the characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and will vary with location and season. Quantified measurements are expressed as an average of measurements taken from a number of individual plants of the new variety. The measurements of any individual plant or any group of plants of the new variety may vary from the stated average.
